Drink cup

ABSTRACT

A drink up consists of a lower cup body, an upper cup body, and a lid. The top of the lower cup body has an opening for holding drink and ice. The upper cup body connects to the lower cup body, with a cup opening for drinking or for a straw to be inserted. The lid closes the cup opening. One adds a drink or ice via the opening into the lower cup body. After the combination of the upper cup body and the lower cup body, one can directly have the drink via the cup opening or a straw. The addition of ice can elongate the keep time of soda gas. The drink therein can be kept at a better taste and coldness for a longer time. By opening the upper and lower cup bodies, the user can readily clean and reuse them. The invention is recyclable.

BACKGROUND OF THE INVENTION

1. Field of Invention

The invention relates to a drink cup and, in particular, to a drink cupthat can elongate the keep time of soda gas in order to maintain abetter taste and coldness for the soda therein for the longer time. Theinvention is also recyclable and environment-friendly.

2. Related Art

Current drinks on the market are often contained in a plastic bottle,which is an integrally formed bottle 11 as shown in FIG. 1. The bottle11 has an accommodating space to hold a drink. The upper part of thebottle 11 has a bottle opening 12 for its user to directly enjoy thedrink or use a straw to drink.

In practice, one can add ice to soda to reduce the loss of carbondioxide and thus maintain a higher gas concentration in the drink. Thesoda in this case has a better taste and coldness. However, the bottleopening of a conventional plastic bottle is too narrow for ice cubes togo through.

Besides, the sofa from a normal soda machine is usually dispensed into apaper cup. Even though the user can add ice in this case, the use ofpaper cups is a waste of recourses.

Usual drink cups for takeout have sealed openings or lids. Both of themcannot be recycled, also a waste of natural resources. In the lattercase, the connection between the lid and the container may not be strongenough and result in leaks. This is extremely inconvenient. It would bea win-win if the takeout drink cup can be recycled after rinse and thevendor advertises a discount when people re-use the takeout drink cupfor next purchases.

SUMMARY OF THE INVENTION

An objective of the invention is to provide a drink cup that isconvenient for its user to add ice, thereby elongating the keep time ofgas in soda and thus maintaining its taste and coldness.

Another objective of the invention is to provide a drink cup that isrecyclable and environment-friendly, avoiding waste of naturalresources.

To achieve the above objectives, the disclosed drink cup includes alower cup body, an upper cup body, and a lid. The top of the lower cupbody has an opening for holding drink and ice cubes. The upper cup bodyis connected to the lower cup body. Its top part has a bottle openingfor its user to drink or a straw to be inserted. The lid closes thebottle opening. One adds a drink or ice via the opening into the lowercup body. After the combination of the upper cup body and the lower cupbody, one can directly have the drink via the cup opening or a straw.The addition of ice can elongate the keep time of soda gas. The drinktherein can be kept at a better taste and coldness for a longer time. Byopening the upper and lower cup bodies, the user can readily clean andreuse them. The invention is recyclable.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will be apparent from the following detaileddescription, which proceeds with reference to the accompanying drawings,wherein the same references relate to the same elements.

Please refer to FIGS. 2 and 3. The disclosed drink cup 20 includes alower cup body 21, an upper cup body 22, and a closing element such as alid 23.

The top of the lower cup body 21 has an opening 211 for forming anaccommodating space to hold a drink and ice cubes.

The upper cup body 22 is connected to the lower cup body 21 to seal theopening 211 of the lower cup body 21. The top part of the upper cup body22 has a drinking opening for the user to drink or a straw to beinserted. In this embodiment, the drinking opening has the shape of abottle opening 221 that can be closed by a sealing element such as a lid23.

The lower cup body 21 and the upper cup body 22 can be integrally formedusing molds separately. They have the advantages of light weight,resistance to external forces, air-tightness, high flexibility,transparency, and being recyclable.

The lid 23 is fastened onto the bottle opening 221 of the upper cup body22 via conventional threads, thereby sealing the bottle opening 221.

The junctions of the lower cup body 21 and the upper cup body 22 furtherhave connecting sections 212, 222 to enhance the sealing between theupper and lower cup bodies 22, 21.

In practice, the connecting section 212 of the lower cup body 21 and theconnecting section 222 of the upper body 22 have threads 213, 223,respectively. The upper cup body 22 and the lower cup body 21 are thusconnected by fastening.

As shown in FIG. 4, the connecting section 212 of the lower cup body 21and the connecting section 222 of the upper cup body 22 are formed witha groove 214 and hooks 224. The upper cup body 22 and the lower cup body21 are then connected by catching.

Alternatively, as shown in FIG. 5, the connecting section 212 of thelower cup body 21 and the connecting section 222 of the upper cup body22 are formed respectively with a protruding rim 215 and an annulargroove 225. The upper cup body 22 and the lower cup body 21 are thenconnected by pressing.

Since the upper cup body 22 and the lower cup body 21 in the embodimentsof FIGS. 4 and 5 are connected by catching or pressing, the junctions ofthem do not need to have a circular cross section.

After adding the drink and ice via the opening of the lower cup bodyinto the disclosed drink cup 20, one connects the upper cup body 22 andthe lower cup body 21 as shown in FIG. 6. Ice cubes 30 and one or moredrinks 40 are thus sealed inside the drink cup 20. There will not be anyleakage even if the drink cup 20 is put sideways or topples over.

To drink the drink, the user only needs to open the lid on the bottleopening and drinks it directly or uses a straw to drink. Since the drinkis kept with ice cubes inside the drink cup, the low temperature of iceand the sealing effect of the drink cup can elongate the keep time ofthe carbon dioxide. The drink therein can thus maintain its taste andcoldness for a longer time.

The user can open the upper and lower cup bodies and clean them. Theyare reusable. The invention is thus recyclable and moreenvironment-friendly.

Although the invention has been described with reference to specificembodiments, this description is not meant to be construed in a limitingsense. Various modifications of the disclosed embodiments, as well asalternative embodiments, will be apparent to persons skilled in the art.It is, therefore, contemplated that the appended claims will cover allmodifications that fall within the true scope of the invention.
